What is allowed in carry-on baggage?
Souleymane Enok
Preparing your carry-on luggage is an essential step before flying, but it often comes with many questions. Liquids, electronic devices, personal accessories, food, medicines… The rules can seem vague and sometimes vary depending on the airline or airport. A question then arises systematically for travelers: what is actually allowed in carry-on luggage?
Carry-on luggage is subject to strict security rules, primarily implemented to ensure the safety of passengers on board. These rules concern both the type of items transported and their quantities, formats, or packaging. For example, an item authorized in checked luggage may be prohibited in the cabin, and vice versa.
Failing to anticipate these restrictions can lead to inconveniences: items confiscated at the security checkpoint, loss of time at the airport, or even unnecessary stress before boarding. Conversely, knowing exactly what is allowed allows you to travel with more peace of mind, optimize the space in your carry-on bag, and avoid any unpleasant surprises.
Between the rules on liquids, electronic devices, skincare products, personal accessories, or even specific items like medicines or food, it is essential to take stock before packing your luggage.
In this article, we will review everything that is allowed in carry-on luggage, explain the main rules to know, and help you prepare a bag that is compliant, practical, and adapted to your trip.
Which items are strictly prohibited in carry-on luggage?
When preparing carry-on luggage, it is essential to know the strictly prohibited items, because they will be systematically confiscated at the security checkpoint, with no possibility of recovery. These restrictions are put in place to ensure the safety of passengers and the crew on board the aircraft. They apply in almost all international airports, although some details may vary slightly.
Items prohibited in the cabin are primarily those that can represent a potential danger: sharp, blunt, flammable, explosive objects, or those likely to be used as a weapon. Many travelers are surprised to see everyday items refused, as their dangerous nature is not always obvious at first glance.
It is important to understand that the format, quantity, or personal use do not generally come into play. Even a small item can be prohibited if it falls into a category deemed dangerous. Furthermore, security personnel apply the precautionary principle: in case of doubt, the item is refused.
Some items are authorized in checked luggage but are strictly prohibited in the cabin, which explains why it is recommended to distribute your belongings well between carry-on and checked luggage. Not respecting these rules often leads to the permanent loss of the item concerned.
Here is the list of items strictly prohibited in carry-on luggage:
- Firearms, real or replica
- Ammunition
- Bladed weapons (knives, daggers, sabers, bayonets)
- Long-blade scissors
- Unprotected razor blades
- Box cutters
- Sharp or pointed tools (screwdrivers, DIY scissors, pliers)
- Blunt objects (batons, bats, clubs)
- Flammable aerosols
- Gasoline and fuels
- Fireworks
- Explosives
- Detonators
- Toxic chemical products
- Corrosive substances
- Flammable paints
- Solvents
- Unauthorized compressed gases
- Storm lighters
- Gasoline lighters
- Matches in large quantities
- Defense weapons (tear gas, pepper spray)
- Tasers
- Realistic replica weapons
- Objects disguised as weapons
Even if some of these items seem obvious, others can be surprising. For example, a simple multi-tool or a small souvenir knife can be considered a bladed weapon. The rules do not take into account the traveler’s intention, but only the potential for danger.
It is also important to note that security agents have the final say. An item tolerated in one airport may be refused in another, depending on the interpretation of the rules or the level of vigilance. That is why it is always better to take no risks and place any questionable item in checked luggage or leave it at home.
Finally, to avoid any unpleasant surprises, it is advisable to check the rules before departure and to prepare your carry-on luggage with care. Anticipating these prohibitions allows you to save time at security, travel with more peace of mind, and avoid the frustration associated with the confiscation of personal items.
In summary, the items strictly prohibited in carry-on luggage are those that present a risk to safety, whether they are sharp, flammable, explosive, or can be used as a weapon. Knowing them in advance is the best way to avoid inconveniences at the airport.
Which items are allowed in carry-on luggage under certain conditions?
Many items are authorized in carry-on luggage, but only under certain strict conditions. These rules aim to reconcile aviation safety and passenger comfort. They mainly concern the quantities, packaging, format, or even the personal use of the items transported. Failure to comply with these conditions can lead to confiscation at the security checkpoint, even if the item is authorized in principle.
The most common cases concern liquids, electronic devices, skincare products, medicines, and certain everyday items. Airport authorities apply harmonized rules, notably the famous 100 ml limit for liquids, but also specific checks for batteries, food, or personal accessories.
It is important to note that conditions may vary slightly depending on the country, airport, or airline. However, the principles remain generally the same: limited quantity, appropriate packaging, and legitimate use. In case of doubt, the security officer remains the decision-maker.
Here is the list of items authorized in carry-on luggage under certain conditions:
- Liquids, gels, and creams in containers of 100 ml maximum
- Liquids grouped in a transparent 1-liter plastic bag
- Liquid toiletries (shampoo, shower gel, perfume) ≤ 100 ml
- Liquid or creamy cosmetics ≤ 100 ml
- Liquid medicines with a prescription or medical justification
- Solid medicines (tablets, capsules)
- Liquid baby food (quantity necessary for the flight)
- Solid food (sandwiches, snacks, fruits)
- Electronic devices (smartphones, tablets, laptops)
- Lithium batteries integrated into devices
- External batteries (power banks) within authorized limits
- Electronic cigarettes (not to be used on board)
- Standard lighter (only one, on your person)
- Short-blade scissors (depending on authorized length)
- Disposable razors
- Non-metallic nail files
- Compact umbrellas
- Medical accessories (syringes with a prescription)
- Valuables (jewelry, important documents)
Even when these items are authorized, their presentation at security is essential. Liquids must be easily accessible, electronic devices may be requested separately, and medicines must be justifiable if necessary.
It is also recommended to anticipate checks by placing these items in easily accessible compartments. This helps to streamline passage through the security checkpoint and avoid unnecessary delays.
In summary, many items are allowed in carry-on luggage provided that precise rules are respected. Knowing these conditions allows you to pack your bag intelligently, avoid confiscations, and travel with more peace of mind.

What liquids can be transported in carry-on luggage and how to pack them correctly?
Transporting liquids in carry-on luggage is possible, but only by respecting strict rules imposed by aviation security. These rules aim to limit risks while allowing passengers to take their essential products. Improper preparation almost systematically leads to the confiscation of liquids at security.
The main rule to remember is simple: each container must not exceed 100 ml, even if it is not completely full. All liquids must then be grouped in a transparent, resealable plastic bag with a maximum capacity of one liter. This bag must be able to be presented separately when passing through the security checkpoint.
It is also important to understand that the definition of "liquid" is broad. It includes not only drinks, but also gels, creams, lotions, pastes, and semi-liquid substances. Many everyday products are therefore concerned.
Here is a summary table of liquids allowed in carry-on luggage and the conditions to be met:
| Type of liquid | Cabin authorization | Conditions to meet |
|---|---|---|
| Water, juice, sodas | Yes | Container ≤ 100 ml, in the plastic bag |
| Perfume | Yes | Bottle ≤ 100 ml, in the plastic bag |
| Shampoo, shower gel | Yes | Container ≤ 100 ml, in the plastic bag |
| Cream, lotion, liquid makeup | Yes | ≤ 100 ml, in a plastic bag |
| Toothpaste | Yes | Tube ≤ 100 ml |
| Liquid medication | Yes | Prescription or medical proof recommended |
| Milk, baby juice | Yes | Quantity required for the flight, no strict limit |
| Alcohol purchased before security | Yes | ≤ 100 ml and in a plastic bag |
| Alcohol purchased duty-free | Yes | Sealed, with proof of purchase |
| Liquid food (soups, sauces) | Yes | ≤ 100 ml, in a plastic bag |
To prepare your liquids properly, it is advisable to use travel containers, check the volumes indicated on each bottle, and not exceed the total permitted capacity of the bag. All passengers are entitled to one single one-liter bag.
It is also recommended to place this bag in an easily accessible compartment of your cabin bag so that it can be removed quickly at security. This saves time and avoids unnecessary handling.
In summary, liquids are allowed in carry-on baggage provided that the volumes, packaging, and presentation requirements are met. Good preparation is the key to getting through security without stress and traveling with peace of mind.
Conclusion
In conclusion, knowing what is allowed in carry-on baggage is essential for traveling with peace of mind and avoiding unpleasant surprises at the airport. Between strictly prohibited items, those allowed under conditions, and specific rules concerning liquids, good preparation helps save time, avoid confiscations, and reduce stress during security screening.
The key lies in anticipation. By identifying in advance which items should be placed in checked luggage, which ones to keep in the cabin, and the correct way to pack liquids, you optimize your bag space while complying with current regulations. It is also important to keep in mind that, even if regulations are generally harmonized, security agents always have the final say.
Traveling with a well-prepared carry-on bag also means traveling more comfortably. You keep your essential items within reach, avoid extra fees, and get through security checks faster. A compliant and well-organized carry-on bag contributes directly to a smoother travel experience.
In summary, knowing precisely what is allowed in carry-on baggage allows you to travel in complete tranquility, with an optimized bag that is compliant with the rules and perfectly suited to your needs.
